Hubcaps do not stay on the Matrix. I have lost all 4 of them 3 times now (over a 2 year span). It costs about $50 to replace all 4 if I buy from a private seller I found on ebay. BUT I have replaced them 4 times. I am a very careful driver, I didn't hit anything to knock them off. I see a lot of other Matrix's around tound missing hubs too, so I guess this is a common occurrence. I no longer have hubs on my car because I got tired of shelling out money to replace them. It definitely takes away from the look of the car.
